	A possibility of ultrasonic method to measure flow characteristics Chára, Zdeněk ; Matoušek, Václav Results of velocity-field measurements by the ADV (Acoustic Doppler Velocimetry) probe are presented for various geometrical arrangements (open channel flow, flow behind a rectangular cylinder, flow through a hole in a plate). The measurements are compared with those carried out simultaneously using the LDA method. Detailed record
	Krátký přehled metod identifikace vírů s ohledem na data naměřená 2D PIV Knob, Martin ; Uruba, Václav A brief survey of four basic vortex identification methods, namely the Q- criterion, the l2 method, the G2 method and the Complex eigenvalue method, is given in this contribution. All the methods are investigated on an artificial flow- field as well as an unsteady signal, obtained by the TR PIV system. The results of all the methods are evaluated and compared. Detailed record
	Experimental study of of time development of pulsatile jets using classical PIV method Kopecký, V. ; Kotek, M. ; Pírková, L. ; Jašíková, D. ; Trávníček, Zdeněk ; Hlína, Jan This paper describes a quantitative visualization of pulsatile flow fields using classical PIV method. A synchronization of PIV measurement with the control signal allows to acquire flow fields maps with time steps less than 1ms. The results are presented for jets from weaving nozzles, for controlled jets, and for plasma arks for electrostatic spinning. Detailed record
